From the Pena Palace towers above Sintra's misty hills to the Roman ruins of Conimbriga to watching the Atlantic sunset from the Cabo de São Vicente cliffs at Europe's southwestern tip, the Portugal eSIM from ZetSIM provided reliable coverage for every remarkable stop.

Shared the hotspot from my Portugal eSIM on the Alfa Pendular train from Lisbon to Porto. Two of us connected for the three hour journey along the Tagus estuary and Atlantic coast. ZetSIM on Portuguese trains seamless.

Used ZetPass for the Portugal eSIM at half price. Five weeks from the Minho river valley to the Alentejo cork forests to the Madeira island peaks data throughout. ZetPass makes one of Europe's best value destinations even better value.

Got the Portugal Data + Voice + SMS plan called a local surfing school in Ericeira, got Porto wine lodge texts, and had data for Lisbon's transport apps. That combination made Portugal very easy to explore end to end.

Portugal eSIM from ZetSIM activated before the Lisbon flight and had a local connection at Humberto Delgado Airport before the Metro reached Marquês de Pombal. Quick and affordable.
